nrcrnn STATES PATENT IMPROVEMENT IN HOUSE-VENTILATION.

Specification forming part of Letters Patent No. [80,019, dated July 18,1876; application filed April 11, 1876.

To all whom it may concern:

Be it known that I, WILLIAM HQ'FLUDDER, of Newport, Rhode Island, haveinvented a new and Improved System of Soil-Pipe, Water- Closet, andother Waste-Pipe Ventilation for Dwellings, Houses, and other Buildings,of which the following is a specification:

Sheet 1 of the accompanying drawings is a diagram representing a portionof a dwellinghouse in which the general arrangement of my improvedsystem is shown.

The object of my invention is to create and apply a downward current ofair-in and through the length of soil-pipes,water-closet or otherwaste-pipes of dwellings, houses, and other buildings, by means eitherof a ventilating-flue, to be constructed in connection with the kitchenor other flue or chimney in which there is heat at all seasons, or to beprovided with other suitable means of inducing a permanent draft in onedirection-and that downward with the flow-as, for instance, by the useof a fire or flame, or steam, either inside or outside the flue orshaft, a ventilatingcowl on the ventilating flue or shaft, or ofothermechanical appliances by which air may be displaced at or near thebottom of the soilpipe or other waste-pipes. and to supply exter nal airfor this current by extending the soilpipe upward and through the roofto the external air. In order to secure a continuous movement of airdown the inside of the soilpipe A or other waste-pipe, I seal the lowerend of the soil or other waste pipe, as shown at a in the drawing, or bythe usual method of interposing a water or other trap, or itsequivalent, in its course outside the building, to avoid faulty jointsin the pipe leading to the sewer; and near that, or at such other pointas I may determine, I branch out for my ventilating flue or shaft B,which, in this instance, is carried up through the length of thechimney. By thus providing for the heating of the ventilating-flue acontinuous aircurrent down the soil-pipe and up the flue is induced.Near the upper end of the soil-pipe, at the point marked 1), or at anypoint most convenient to accomplish my purpose, I introduce a damper orvalve, 0, or its equivalent, which ordinarily stands open, as shown bythe black lines, but, when operated by the handle or lever of thewater-closet G or D, or its equivalent, and just before the water-pan,

or its equivalent, under the closet G or D uuseals itself, is closed bythe connecting-rod, wire, or its equivalent, (1, connected on the onepart to the handle or lever, and on the other part to the damper. Thenthe air-supply of the ventilating shaft or flue can be furnished only bya downward current through the closets O or D. By this application of avdownward current of air at all times through the soil-pipe, and throughclosets when the latter I fis the handle, which operates, through the"medium of the lever g, the pan of the closet G. The stem of the handleis'prolonged below its point of connection with the panlever, andterminates in a loop, which is held in a cam or irregular slot, h if,formed in the lever-arm h. The latter arm is pivoted at t to a suitablesupport, and is provided near its outer end with a laterally-projectingpin, j, which enters a slot, 70, formed in the lever Z. This lastn'amedlever is pivoted at m to a proper support, and at a is connected by awire, 0, or other suitable intermediary, to the crank or lever c of thedamper c. The loop end of the handle f traverses the irregular slot h W.In traversing the part h it operates the damper; then, traversing h itoperates the pan. For this purpose it is connected with the panlever gby passing loosely through that lever, shoulders f f being formed onsaid handle, one on each side of the lever, and at a proper distanceapart to afford the'needed play.

The operation is as follows: The parts being in .the position shown inFig. 2, with the damper open and the pan closed, on raising the handleits looped end first traverses the part h of the slot, which has theeffect of lifting the lever h, and consequently operating FFIGE. I

pan open and the damper the lever l to close down the damper; then thelooped end traverses the part k of the slot, which it can do withoutfurther moving the damper. But by this further raising of the handle thelower stop f is brought in contact with and serves to raise the panlevcrg,'which has the effect of dropping the pan. Thus, in raising thehandle, the damper is first closed, and then the pan is opened. Indepressing the handle the reverse is the case. The looped end traversesthe part k of the slot without aii'ecting the damper. The upper stop fhow' ever, if the lever 9 does not drop of its own weight, will depressthe lever, and so in any event close the pan. Then the looped end entersthe part It of the slot, bears on and depresses the leverarm h, andconsequently opens the damper. As many wires as there are closets can beconnected with the damperlover a, each having its own connectiontherewith. Inasmuch as the wires or cords 0 are flexible, any one mayoperate the damper, the only effect of the closing of the damper by onebeing that the other connecting cords or wires will be slack.

I11 all closets, except where a water seal or pan is used, there isgenerally enough false motion of the lever and handle to work thedamper-cranks in time; but with the Water seal or pan some mechanicaldevice for obtaining this motion is needed. Such a device is shown inthe drawing in the loose connection of the handle with the pan-lever.

By the application of my system, the possibility of a pressure ofsewer-air from within -the soil'pipe forcing the traps and impregnatingthe water in waste-pipes and waterclosets, bath and wash bowls, now sogenerally the case, is obviated, and the foul air carried oft harmlessto the outer air. I also secure at all times such a downward circulationor current of pure air through the soil-pipe and closets as will preventthe formation of any poisonous gases within the soil or waste pipes, andeii'ectually dilute any gases re ceived from drain or cess'pool beforeit ascends the ventilating shaft or fine. At the point e, or at suchother point most convenlent, Iintroduce a chamber in the ventilatingpipe or flue, having a glass at one side for inspection, and insert inthis chamber, it I wish, a wind-well, or its equivalent, which willindicate the movement of the column of air.

The above system of ventilation, with some modifications, is applicableto sewer-ventilation.

What I claim, and desire to secure by Letters Patent, is as follows:

1. The method of ventilating the soil or waste pipe or pipes ofdwellings and other houses or buildings, by the use of a ventilatingflue or shaft, arranged or provided with means to produce an upwardmovement of the air therein, communicating with the soil-pipe or otherwaste-pipe at or near the bottom of the same, and operating to induce aperma nent current of air downward through the length of the said pipe,and thence upward through said ventilating-shaft, substantially as setforth.

2. The combination of the soil-pipe, the ventilating-shaft, and thedamper in the soil-pipe, connected with and operated by the waterclosetlevers, or their equivalents, at the times and in the mannersubstantially as set forth.

3. The combination, with the soil-pipe or other waste-pipe and theventilating-shaft, arranged and. operating to induce a permanentdownward air-current in the said pipe, as described, of water-closetswithout permanently-sealed water-traps,substantially as set forth.

In testimony whereofI have hereunto sigiied my name this 25th day ofMarch, A. D. 1876.
